IMPROVEMENT IN HOT-AIR REGISTERS.

Specification forming part of Letters Patent No. 167,480, datedSeptember 7, 1875; application filed June 26, 1875.

' To all whom it may concern:

Be it known that I, EDWARD A. TUT'rLE, of the city, county, and State ofNew York, have invented a new and Improved Hot-Air Register, of whichthe following is a specificar tion:

The invention will first be fully described, and then pointed out in theclaim.

Figure 1 is a side elevation of my improved register. Fig. 2 is asection on line 00a: of Fig. 1. Fig. 3 is a section on line y y, andFig. 4 is a section on line 2 2.

Similar letters of reference indicate corresponding parts.

A is the front plate; B, the register; 0, the wall; and G theindependent wall-frame, which is permanently secured in the wall by itsshape, and to which the register is attached by the lugs D and screws E,said lugs being located inside of the front edge of the frame, and saidedge being notched, as repr esented at F, to obtain the requisite spacefor the nuts and screws in the angle between the Wall-plate andregister, while they come together at the front, so as to utilize allthe space inside of the Wall-frame for the register.

By locating the lugs for the screws within the wall-frame they are notobstructed by the plastering, and they do not injure it as they would iflocated on the outside.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination of Wall-frame and registerframe,fitting closely together in front, and having lugs for fastening-screwsin a divergent angle between said frames, as and for the purposespecified.

EDWARD A. TUTTLE.
